* Cobalt, others, in talks on new insurance fund
* Likely to be bigger than existing $1 billion fund
* CEO sees no early resumption of deepwater drilling

LONDON, Oct 7 (Reuters) - U.S. oil explorers are talking about forming a new insurance fund that would cover the costs of any future oil spill, to avoid a scenario where smaller companies are unable to drill offshore, a senior industry executive said on Thursday.
BP's oil spill is expected to rack up an over $30 billion bill for shutting the leak, cleaning up the oil and compensating those affected.
This has prompted concerns about what would have happened if a company without BP's massive resources had been operating the blown-out well.
Jim Farnsworth, Chief Executive of Cobalt International, a small explorer focussed on the deepwater of the Gulf of Mexico, said his company was in talks on a solution to avert such fears.
"It is likely and probably desirable for a combination of us to come together and insure against these types of accidents," he told the Finding Petroleum conference in London.
"Cobalt is actively in discussions along those lines," he added.
Some analysts have predicted that the oil spill could cause a shakeout with smaller companies being forced to sell up because new regulations force them to seek insurance cover which may be either unobtainable or unaffordable.
In the wake of Exxon's Valdez oil spill, companies formed a $1 billion fund to pay for future oil spills. Farnsworth, a former BP executive, said he expected the new fund to be bigger.
Cobalt's market capitalisation has dropped by $1.5 billion, or 30 percent, since the oil spill began, Farnsworth said.
The CEO added that he expected it would take a long time for drilling to resume in the Gulf of Mexico even if a drilling moratorium, installed in the wake of the oil spill, is lifted in November, as expected.
"The real moratorium ends when they start issuing permits again and that could take a long time," he said.
Some analysts predict permitting may remain paralyzed until late 2011. (Reporting by Tom Bergin; Editing by Hans Peters)
